Embodiment Construction
[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements can also be present. When an element is considered to be "connected" to another element, it may be directly connected to the o...

The invention relates to a lock mechanism and an impact tool with the lock mechanism. The lock mechanism is used for locking an impact part so as to constrain the impact motion stroke of the impact part. The impact part can do reciprocating motion along the inner wall of a sleeve, and the sleeve is fixed through a first bearing. The lock mechanism comprises a first lock part provided with a firstelastic part arranged on the inner wall of the sleeve and a second lock part provided with a second elastic part. The first elastic part and the second elastic part are used for absorbing at least part of impact energy of the impact part. The first elastic part and the outer wall of the end, doing impact motion, of the impact part can be in interference fit. The end, with elastic force, of the second elastic part acts on the sleeve, and the other end of the second elastic part acts on the first bearing. According to the lock mechanism and the impact tool, dual locking is achieved through the second lock part and the first lock part so as to reduce lock force to the first lock part, the service life of the first elastic part is prolonged, meanwhile, the locking-hammering effect is improved,vibration of a complete machine is reduced, and operation comfort is improved.
Description
technical field [0001] The invention relates to the technical field of electric tools, in particular to a locking mechanism and an impact tool with the locking mechanism. Background technique [0002] Impact tools are the most common and frequently used tools in the field of power tools, and they are usually used to excavate the surface of objects such as walls and concrete. Impact tools can include electric hammers, impact drills and electric picks, etc., which mainly transmit the torque of the motor to the impact mechanism through the transmission mechanism, and then drive the working head to reciprocate to realize the impact function. [0003] At present, the locking of the impact part in the impact tool is mainly through the use of an O-ring for locking. The impact part contacts the O-ring during the impact movement. At this time, the O-ring and the impact part have an interference fit to reduce part of the impact force of the impact part. In the prior art, when the O-r...
