Abstract
The utility model relates to a foldable assist handle for electric tool which pertains to the area of the machine in the industry of electric tool. According to the design scheme provided in the utility model, one end of the assist handle is made of two parallel flat boards, the heads of the two boards are both rounded with a pair of concentric holes at the same position on each board, one end of the link rod of the handle is a flat board with a rounded hole to be inserted into the space between the two boards of the assist handle to be integrated with the two boards by a connector. A groove is arranged on the rounded top of the flat board of the handle and at a position away from the top by 90 degrees to be through the board at the transverse direction, an oval countersunk fillister head through hole is provided at the middle of the other end of the assist handle to contain a ball and then a ball positioning spring. The utility model can be folded after a 90 degrees rotation. The positioning is steady. The rotation is smooth. The occupied space is effectively reduced. The dimensions of the packing are reduced. And the frequent demounting is not needed. So, the practicability is greatly improved and the work efficiency as well as the grade of the product is improved.
Description
Technical field
The utility model relates to electric tool, specifically the improvement that the handle on the electric tool is done.
Background technology
According to ergonomics motion and Changing Pattern, impact the general modes that adopt additional assist handle of electric tool such as drill gun, when making right human hand grip the percussion drill use, available left hand is firmly auxiliary, avoid causing the chance of spraining, rationally decompose because of the motor tangential moment that torsion causes that runs up to human body because of machine torsion is excessive.Existing assist handle is monolithic construction, can take up room on the packing, therefore when packing, generally it can be pulled down independent packing, with the minimizing packaging volume, but the easy like this disappearance parts that cause; Must set up it when needing to use, assembly technology is more loaded down with trivial details, inconvenience, as run into inapplicable occasion, and also must disassemble again, practicality, convenience are all bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, designs a kind of folding assist handle convenient to use.
According to design provided by the utility model, one end of assist handle is two blocks of flat plates arranged side by side, form the flat plate end of assist handle, in two flat wrench portions one concentric circular hole is set, one end of handle and connecting rod is round-meshed flat, form the flat end of handle and connecting rod, between two blocks of flat plates on the flat end insertion assist handle of handle and connecting rod, the connector that assist handle and handle and connecting rod utilization are inserted in the circular hole is hinged.
The flat end of handle and connecting rod is rounded to arc, and at curved end and turn over 90 ° and be in and have a groove on the thickness direction, the flat plate termination portion of assist handle is rounded to arc equally.A through hole is arranged in the assist handle, put into ball and retainer spring successively in through hole, utilize screw to fix in the outer end of through hole again, ball contacts with the flat curved end of handle and connecting rod.
The other end of handle and connecting rod is a polygonal axle, axle head has screw thread, the polygon shaft of handle and connecting rod is installed on the front shroud, and front shroud is installed on the electric tool casing, and a polygon through hole that is used to install polygon shaft that matches with polygonal axle is arranged in the lower end of front shroud.The bonnet that is used to cover through hole at assist handle with respect to the other end connection of flat plate end.
The utility model has the advantages that: assist handle is collapsible, promptly can realize 90 ° of rotations, and 0 ° clear with 90 ° two grades location, and rotation is flexible.Now be applied to impact the aid that electric tool such as drill gun uses operation, electric impacting is drilled on the armed basis of the right hand, has increased the auxiliary position of helping of left hand, freely realize the horizontal or vertical multistation operation that waits, reliability strengthens, and operating efficiency is further improved.The utility model is rotatable 90 ° of placements when not using, and effectively reduce the locus, reduce Package size, and after once assembling, do not need frequent dismounting, have improved the practicality of product greatly, have improved the class of operating efficiency and product.
Description of drawings
Fig. 1 is the utility model assembling explosive view.
Fig. 2 is the utility model working state schematic representation.
Fig. 3 is the utility model off working state schematic diagram.
The specific embodiment
The utility model mainly is made up of parts such as front shroud 1, handle and connecting rod 2, nut 3, assist handle 4, ball 5, needle roller retainer spring 6, self-tapping screw 7, handle bonnet 8, bolt 9, nuts 10.
As shown in Figure 1, assist handle 4 one ends are two blocks of flat plates arranged side by side, and there is a concentric circular hole at two flat wrench portion's roundings and same position place, handle and connecting rod 2 one ends are round-meshed flat, and the head rounding inserts between the two flat plates of assist handle 4, by circular hole, connect with connector.
Handle and connecting rod 2 flat rounded apex and turn over 90 ° and be in and have a groove on the thickness direction; A countersunk raised head through hole is arranged in the middle of assist handle 4 other ends, put into ball 5 and needle roller retainer spring 6 successively, be fixed on the relevant position of assist handle 4 inside by self-tapping screw 7, ball 5 promptly exposes with handle and connecting rod 2 flat head fillet touching positions in the middle of two blocks of flat plates arranged side by side from the through hole other end.
Front shroud 1 is installed on the casing of electric tool, and it is an identical polygonal end axle that a polygon through hole, handle and connecting rod 2 other ends are arranged in the lower end of front shroud 1, and axle head has screw thread, passes on the front shroud 1 in the corresponding polygonal hole, and is fastening by nut 3.Assist handle 4 one ends link to each other with handle bonnet 8.
As shown in Figure 2, when preparing to use, assist handle 4 is rotated to and the fuselage vertical direction, make the ball 5 in the assist handle 4 just in time corresponding, form certain location with groove in the middle of handle and connecting rod 2 heads, the plane of the flat plate on the assist handle 4 just in time with handle and connecting rod 2 on the flat plane paste mutually, when handle is exerted oneself forward, because handle and connecting rod 2 supports, stressed reliable, guarantee service life.
When special occasions or when not using, with assist handle 4 along bolt 9 inside half-twists, make assist handle and the consistent direction of fuselage maintenance level, and a groove is also arranged in handle and connecting rod 2 corresponding 90 ° of directions, balls 5 in the assist handle 4 are just in time fallen in the groove in the handle and connecting rod 2, form one 90 ° location, and can not have influence on the gripping of operator's right hand.
Because there is ball 5 to snap in handle and connecting rod 2 head recess location, so 0 °, 90 ° two grades are clear; Handle and connecting rod 2 withstands the compression needle roller retainer spring 6 of ball 5 when rotated, makes ball 5 withdraw from groove, rolls into 90 ° along handle and connecting rod 2 head fillets and locates groove, rotates flexible.
