Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment:

the knocking hammer for civil engineering shown in fig. 1-4 comprises a hand lever 1, a connecting rod 2 and a hammer head 3, wherein the hand lever 1 comprises a handle 11 and an arc-shaped rod 12, a first sliding sleeve 13 is arranged on the arc-shaped rod 12, the arc-shaped rod 12 is in sliding fit with the first sliding sleeve 13, the arc-shaped rod 12 is fixed with the first sliding sleeve 13 through a bolt 14, the handle 11 is fixed at the bottom of the first sliding sleeve 13, a supporting plate 15 is fixedly arranged at the top of the arc-shaped rod 12, the connecting rod 2 is fixed at the top of the supporting plate 15, a stud 21 is fixedly arranged at the top of the connecting rod 2, the hammer head 3 is in threaded fixation with the stud 21, a second sliding sleeve 22 is arranged on the connecting rod 2, the second sliding sleeve 22 is in sliding fit with the connecting rod 2, the second sliding sleeve 22 is connected with the supporting plate 15 through a first spring 23, a clamping block 24 is fixedly arranged at the top of, the latch hole 31 is correspondingly engaged with the latch 24.

Preferably, the handle 11 is a telescopic rod body, and the handle rod 11 adopts a telescopic rod body with a double-rod sleeving structure and is locked and fixed through bolt adjustment.

Preferably, a plurality of pin holes 16 are formed in the arc rod 12, the pin holes 16 are matched with the bolts 14, and the plurality of pin holes 16 can facilitate the fixation of the first sliding sleeve 13 after multi-angle adjustment.

Preferably, the latch 14 is connected with the first sliding sleeve 13 through the second spring 17, and the latch 14 is connected with the first sliding sleeve 13 through the second spring 17, so that the latch 14 is prevented from being lost.

Preferably, rubber sleeve 25 is arranged on the outer side of fixture block 24, so that the clamping force between fixture block 24 and clamping hole 31 can be improved under the action of rubber sleeve 25, and the phenomenon that the joint of the fixture block is loosened to influence the reinforcing effect of the fixture block on hammer head 3 is avoided.

Second embodiment:
