SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electronic crab-bolt strikes hammer mainly solves the problem that the low time limit for a project of expansion anchor installation efficiency among the current construction installation that exists among the prior art.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides an electronic crab-bolt strikes hammer, includes and strikes the hammer body, still includes one end and expansion anchor butt joint, the sleeve of the other end and this body coupling of hammer to and with strike hammer body swing joint and be used for fixed telescopic lid.
Further, the sleeve comprises a sleeve in butt joint with the expansion anchor bolt, a connecting rod with one end connected with the bottom of the sleeve, and a pin block connected with the other end of the connecting rod and connected with the cover body, wherein the width of the pin block is larger than the diameter of the connecting rod.
Furthermore, the pin block is positioned at the end of the connecting rod and is inclined.
Further, the connecting rod runs through the sleeve pipe bottom and sets up, wherein, sleeve pipe bottom and connecting rod threaded connection.
Specifically, the lid middle part is seted up and is used for passing the round pin piece and the middle part is the rotatory via hole of circular convenient round pin piece to and set up inboard the draw-in groove that is used for spacing round pin piece at the lid, wherein, the circular and connecting rod size matching in via hole middle part.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the utility model discloses an install the sleeve on the impact strut of current strike hammer body, then telescopic other end and expansion anchor butt joint, insert the one end of expansion anchor in the pre-buried hole, during the residual part got into the pre-buried hole under the impact action of striking hammer body, because sleeve and expansion anchor butt joint, consequently when assaulting, can not influence the screw rod at expansion anchor middle part, just can not influence the screw thread on the screw rod simultaneously yet, consequently the utility model discloses both practice thrift the manpower, also improved the installation effectiveness simultaneously.
(2) The utility model discloses a connecting rod and sleeve pipe bottom threaded connection, its effect is the sleeve pipe of different diameters size of conveniently changing to satisfy the installation of not unidimensional expansion anchor bolt, the practicality is stronger.
(3) The utility model discloses a be the centre of a circle in the via hole of lid, the convenience is rotatory after the round pin piece inserts the lid, sets up simultaneously and can fix the round pin piece at the inboard draw-in groove of lid, consequently can not take place to remove when strikeing the impact bar impact round pin piece in the body, and stability is strong, has also guaranteed simultaneously that the expansion anchor bolt of connecting at the sleeve opposite side can not appear the condition emergence of slope in the picture that gets into the pre-buried hole.

Detailed Description
The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
Examples
As shown in fig. 1 to 3, an electric anchor bolt knocking hammer comprises a knocking hammer body 1, a sleeve 2 with one end in butt joint with an expansion anchor bolt and the other end connected with the knocking hammer body 1, and a cover body 3 movably connected with the knocking hammer body 1 and used for fixing the sleeve 2. The sleeve 2 comprises a sleeve 4 butted with the expansion anchor bolt, a connecting rod 5 with one end penetrating through the bottom of the sleeve 4 and in threaded connection, and a pin block 6 connected with the other end of the connecting rod 5 and connected with the cover body 3, wherein the width of the pin block 6 is larger than the diameter of the connecting rod 5. The lid 3 middle part is seted up and is used for passing round pin piece 6 and the middle part is circular make things convenient for round pin piece 6 rotatory via hole 7 to and set up the draw-in groove 8 that is used for spacing round pin piece in 3 inboards of lid, wherein, the circular and 5 size matchs of connecting rod in via hole 7 middle part.
The utility model provides a percussion hammer body 1 is current ordinary percussion hammer in fact and gets rid of drill bit auger bit flower position.
