As shown in Figures 4-6: the workbench 10 is made of wood and has a tripod. Wherein the workbench 10 is a conventional component, which includes a front panel 11, a back panel 12 and a tripod 13, and a screw seat 14 is arranged above each of the two legs 13 on the left and right sides, and a screw rod 15 is received in the hollow interior to drive a The slide block (not shown) slides, and the slide block is fixed below the lower bearing seat 161 of a turning device 16, as shown in Fig. It can be moved back and forth, and the lower bearing seat 161 of the front panel 11 is directly locked on the top surface of the screw seat 14 and is fixed; the back panel 12 can be moved to facilitate adjustment of the clamping distance, and the front panel 11 and The backstage board 12 can be turned over to accommodate work objects or tools of different sizes. In addition, the upper bearing 162 and the lower bearing 161 of the turning device 16 can be nested with each other, and can be pivoted by a shaft 163 It can be rotated relative to each other, and another positioning member 164 can be positioned in a pressing or fitting manner, so that the front panel 11 or the back panel 12 can be positioned at a preset position between 0° and 90°.

The front panel 11 of the present embodiment is generally a wooden board with a predetermined thickness, its middle area is provided with a longitudinal axis hole 111, and its side is provided with a pin hole 112 at a predetermined distance; the side of the front panel 11 Then be provided with a positioning hole 113 in addition; On the front panel 11, a predetermined position is provided with an indicator 114 for positioning angle; In the upright or inclined state, it can be used for the back of the work object against the baffle; the so-called baffle means that it can be fixed upright on the workbench, and its middle area is provided with a rotating seat 30 and one end of the hand saw 51. A notch of 121.

The angle plate 32 of the swivel seat 30 has an arc-shaped positioning part 321 and an angle scale 322 in addition, and the arc-shaped positioning part 321 also selects a crescent-shaped positioning groove; the swivel seat 30 is arranged on the front panel 11 On the top surface, a shaft 315 is provided at the predetermined center of rotation, which can be connected with the shaft hole 111 of the front panel 11, and can provide the rotation of the rotating seat 30 on the top surface of the front panel 11, so as to adjust the level of sawing Angle of direction inclination; the base plate 31 of the swivel seat 30 is provided with a perspective window 36 at a predetermined position, through which the indicator 114 on the front plate 11 can be seen.

The arc-shaped positioning part 321 of the angle plate 32 is pressed and positioned by a movable positioning member 37 fixed on the front panel 11. The positioning member 37 is a bolt that runs through the arc-shaped positioning part 321 from top to bottom. The crescent-shaped positioning groove and the locking hole 112 are screwed together with the lower nut 371 so that the rotating base 30 is fixed at a predetermined angle.

The two bearing seats 69 are two, which are generally flat worktables. When placed on both sides of the front panel 11, they have a worktable that is close to the height of the swivel seat 30 and can be docked, and can bear work objects; An end close to the swivel base 30 forms a beveled edge 691 that gradually increases outward to form a fan-shaped opening.

The two bearings 69 are arranged on both sides of the swivel base 30 in the form of a flat plate, and a plate is directly used as a backrest baffle, so it has the economical and practical effect of combining the hand saw machine with the workbench.

As shown in Figures 7-9, the main difference of this embodiment is that the front panel 11 is further equipped with a quick positioning assembly that can rotate upwards at a fixed angle. The quick positioning group includes a cylinder 71 that can be inserted into the front panel In the positioning hole 113 on the side of the lock hole 112 of 11, a connected large round hole 711 and a small round hole 712 are provided in the cylinder body 71 from top to bottom, and a positioning pin 73 is inserted into a spring 74 from the bottom thereof. Then penetrate the large circular hole 711, utilize the shoulder 732 formed by the larger bottom surface of the pin head 731 to withstand the top of the spring 74, and the bottom of the positioning pin 73 continues to pass through the small circular hole 712, and protrudes to the outside of the cylindrical body 71. A pin hole 734 is arranged horizontally at the predetermined position of the bottom of the positioning pin 73, for a locking pin 738 to be inserted, and partly protrudes from the outside of its both sides; 737 are screw-fixed; and the bottom surface of the front edge of the angle plate 32 is provided with one or more locking holes 75 according to a predetermined angle; In the transverse groove 713, at this time, when the positioning pin 73 is moved upward by the force of the spring 74 pushing up against the shoulder 732, the pin head 731 protrudes upwards and falls into the locking hole 75, so that the angle plate 32 is supported. Detented while being positioned at a set fixed angle.

If the handle 737 is moved downwards and the locking pin 738 is rotated ninety degrees, the locking pin 738 will be locked on the bottom surface 714 of the cylinder 71 and cannot be raised. At this time, the pin head 731 is located in the large round hole 711 In this case, the function of fixed angle positioning is lost. Of course, the screw fixing of the positioning member 83 is still reliable at this time, and the function of positioning at any angle can be achieved.

As shown in Figures 10 and 11: the main difference is that the arc-shaped positioning part 81 of the swivel seat 80 is a lock hole, and a crescent-shaped positioning groove 82 is provided on the side of the shaft hole 111 of the front panel 11; And after the bolt of a locating member 83 penetrates through the lock hole 81 and the locating groove 82 from top to bottom, another nut 84 is used to screw it; Angle scale 86 on the front panel 11.

Fig. 11 illustrates that a baffle plate 90 can also be clamped in the middle of the front panel 11 and the back panel 12, so that the back of the work object can be used against the baffle plate, and the middle area of the baffle plate 90 must also be provided with a swivel seat 30 and A gap 91 through which one end of the hand saw 51 passes.
