Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a portable expanded bottom crab-bolt mounting tool, includes crab-bolt screw rod 1 and expansion head 2, and expansion head 2 fixed connection is in the left end of crab-bolt screw rod 1, and the outer end of crab-bolt screw rod 1 is connected with installation mechanism.

The mounting structure includes sleeve 301, expansion piece 302 and strike pole 303, and sleeve 301 sliding connection is in the outer end of crab-bolt screw rod 1, and expansion piece 302 fixed connection is in the left end of sleeve 301, strikes pole 303 and is connected in the right-hand member of crab-bolt screw rod 1. The left end of the inner wall of the expansion sheet 302 is provided with a round angle. So that the sleeve 301 is left-slid outside the anchor bolt 1, and when the inner end of the expansion piece 302 at the left end of the sleeve 301 is in contact with the outer end of the expansion head 2, the expansion piece 302 is slightly expanded along the outer side of the expansion head 2.

The inside left end of strike pole 303 is seted up flutedly, strike the inside position that is located the recess right-most end of pole 303 and seted up the observation hole, and the structure of observation hole is not limited to the round hole, the semicircle orifice, the waist round hole, square hole, abnormal shape hole etc. can be arbitrary irregular hole type, the outside of crab-bolt screw 1 and the inboard sliding connection of recess, and under the expansion piece 302 unexpanded state, strike the pole 303 and slide to the outside of crab-bolt screw 1, the tail end of crab-bolt screw 1 has not moved to the recess and has seted up the observation hole department, under expansion piece 302 expansion completion state, the tail end of crab-bolt screw 1 can be moved to the recess and seted up the observation hole department. Therefore, when the knocking rod 303 is sleeved to the right end of the anchor bolt screw 1 and the anchor bolt screw 1 is nailed into concrete, the knocking rod 303 can be positioned outside the anchor bolt screw 1 and moved to the tail end of the anchor bolt screw 1 to be in the observation hole only after the expansion of the expansion sheet 302 is completed, so that whether the bottom expanding anchor bolt is installed in place can be confirmed.

The staff: when the anchor bolt is used, the knocking rod 303 is held by a hand and then is knocked, so that the expansion piece 302 at the left end of the sleeve 301 is pushed to slide along the outer end of the expansion head 2 until the knocking rod 303 is positioned at the outer side of the anchor bolt screw 1 and moves to the observation hole position at the inner side of the groove when the tail end of the anchor bolt screw 1 appears, and at the moment, the expansion of the expansion piece 302 is completed, and meanwhile, the installation of the expanded anchor bolt is completed.
