Problems solved by technology
However, there are some disadvantages in this design. When the key is turned, the angle of the pick is not large enough, so that the distance from which the ejector rod extends out of the electromagnet is too small. As a result, the relevant parts in the safe cannot move and disengage with the lock bolt. box, i.e. the safe cannot be opened

The invention provides an improved pulling sheet, and belongs to the technical field of machinery. The improved pulling sheet solves the problem that the design of the existing pulling sheet used for a safety box is unreasonable. The improved pulling sheet comprises a connecting part and a work part, wherein the connecting part and the work part are connected into a whole, a through hole is formed in the connecting part, two clamp blocks in opposite arrangement are fixedly arranged on the inner wall of the through hole, the outer surface of each clamp block consists of a first plane, a second plane and a top edge for connecting the first plane and the second plane, the top edges of the two clamp blocks are in parallel arrangement, in addition, the top edges of the two clamp blocks and one diameter of the through hole are positioned in the same plane, and the located plane of the top edges of the two clamp blocks is arranged in a way that an included angle is formed between the plane and the located plane of the connecting part. The improved pulling sheet has the advantages that the design is reasonable, and the unlocking effect is good.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to an improved pick, in particular to an improved pick used in safes. Background technique [0002] Anti-theft safes on the market are generally divided into two types: mechanical insurance and electronic insurance. Both types of safes achieve the purpose of unlocking by controlling the telescopic ejector rod of the electromagnet. Among them, the mechanical safety is to drive the plectrum to drive the ejector rod to extend out of the electromagnet by means of a key unlocking, thereby opening the safe. [0003] An existing pick used for a safe has one end connected to the lock cylinder and the other end connected to the push rod. When the key rotates with the lock cylinder, the pick will rotate thereupon and move vertically upwards with the push rod. However, there are some disadvantages in this design. When the key is turned, the angle of the pick piece is not large enough, so that ...
