Abstract

The invention discloses a cross-shaped hidden bolt and a mounting tool thereof. The cross-shaped hidden bolt comprises a shell body, a rotating shaft arranged in the shell body in a sleeving manner, and a turnplate fixedly connected with the rotating shaft, wherein the rotating shaft is arranged on two ends of the turnplate in a penetrating manner, the front end, positioned on the turnplate, of the rotating shaft is fixedly connected with a driving disc, the rear end, positioned on the turnplate, of the rotating shaft is connected with a bearing inner ring, a bearing outer ring is connected with a sleeve sheathed outside the rotating shaft, plane threads are arranged on a driving plane of the driving disc, four guide channels which are arrayed along the circumferential direction of the central axis of the rotating shaft and are separated by 90 degrees are arranged on the end surface where the shell body is in parallel to the driving disc, locking blocks are matched in the guide channels and respectively consist of a shift block and a clamping block, threads matched with the plane threads are arranged on the end surface, facing towards the driving disc, of the shift block, the clamping block consists of two clamping plate bodies which are perpendicularly arranged, and the perpendicular point of the four clamping plates bodies are connected with the central axis of the rotating shaft at a 90-degree interval.

Description

technical field [0001] The invention relates to a mechanical connector, in particular to a cross-shaped hidden bolt, and also to a tool for installing the bolt. Background technique [0002] Bolt is one of the most common fasteners, which consists of a head and a screw. The screw rod is cylindrical and has external threads for use with nuts. Bolts and nuts are used together to connect and secure two parts with through holes. Bolts can be divided into hexagon head bolts, round head bolts, square head bolts, countersunk head bolts, etc. according to the head shape. [0003] The existing bolt head adopts a structure protruding from the screw rod, which has a low protection level and poor anti-theft performance. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a cross-shaped concealed bolt with a high protection level and a certain anti-theft effect, and to provide a quick installation ...
