Split type handle head of ratchet wrench and assembling method

Abstract

The invention belongs to the technical field of ratchet wrench design, and particularly relates to a split type handle head of a ratchet wrench. The split type handle head comprises a wrench handle and a wrench head portion with a round expanded end, a longitudinal hole is formed in the wrench head portion, longitudinal teeth are annularly arranged on the inner edge of the hole, the split type handle head is installed in the hole, and the split type handle head comprises an upper cover and a lower cover. A positioning column, a clamping piece and a positioning bolt used for limiting the positioning column and the clamping piece are installed between the upper cover and the lower cover, the positioning bolt sequentially penetrates through the upper cover and the positioning column from top to bottom to be in threaded connection with the lower cover, the positioning bolt sequentially penetrates through the upper cover and the clamping piece from top to bottom to be in threaded connection with the lower cover, and the clamping piece rotates relative to the positioning bolt. According to the split type handle head of the ratchet wrench, the handle head of a new concept is provided, split manufacturing and split assembling are achieved, traditional processes such as turning, planing and milling are not adopted, raw materials are greatly saved, the production cost is reduced, and the split type handle head has the advantages of being simple in structure, easy to manufacture, easy to assemble, easy to maintain and low in manufacturing cost.

Description

technical field [0001] The invention relates to a split handle of a ratchet wrench and an assembly method thereof. It belongs to the technical field of ratchet wrenches. Background technique [0002] In the commonly used ratchet wrench, it is mainly provided with an accommodating groove at the head end of the wrench, and a ratchet assembly, a locking block and a toggle plate can be assembled respectively in the accommodating groove, and the front end of the locking block is provided There are several locking teeth, which can be locked against the ratchet assembly. A chute is recessed in the center of the top edge of the locking block. A spring seat is provided at the bottom edge of the rear end of the toggle plate. The front surface of the spring seat is recessed. There is a hole, which can just accommodate a spring, and the front end of the spring can just be inserted into the chute, so that the locking block can be retracted along the axial direction of the spring, which ...
