Description

Combined drive tool

technical field

The utility model relates to a combined driving tool, in particular to a combined driving tool which can be used for driving screw parts.

Background technique

With the development and progress of science and technology, people's requirements for things have changed from the old thinking of "just use it" to quite delicate. Only the concept of continuous improvement or innovation will produce new forms to increase the added value of products. Only by effectively reducing costs can we survive under the test of fierce market competition.

With reference to Annex 1 US Patent No. 3376768 "LINKAGE BAR FOR WRENCHES" patent case, it includes a bar 1 and two wrenches 15, 16 that can be combined in the bar 1. The combination between the two wrenches 15, 16 and the rod 1 is through the tight fit between the boss and the hole. However, this tight fit clamping structure makes the loading and unloading of the wrench 15, 16 more time-consuming and laborious, and after a long period of wear and tear, The clamping force between the two wrenches 15, 16 and the rod 1 also decreases accordingly, and can no longer be tightly combined. And this clamping structure that utilizes pressing fit makes the combination thickness between the spanners 15, 16 and the rod 1 thicker, which is not conducive to the operation in the narrow space, and is not easy to use and practical.

With reference to Annex 2, US Patent No. 5,996,448 "SOCKET WRENCH" patent case, it is composed of a handle portion 2 with a first handle 8, a rigid extension device 20 and a ratchet head 30. The combination between the rigid extension device 20 and the ratchet head 30 is fixed by a steel ball bounced by a spring (not shown in the figure). However, the clamping force of this steel ball clamping combination is not strong enough. Because the steel ball is in smooth contact with the inner wall of the hole 32, this contact friction is rather weak, and cannot provide good longitudinal anti-loosening locking, and the rigid extension device 20 is very easy to accidentally disengage from the ratchet head 30 during use. , causing the operator to be injured, it is not safe and reliable.
