Prior art there is also the bolt of some slotted heads, laborsaving installation need to be carried out by corresponding instrument, the termination slotting bolt of such as Patent No. CN201220599564.8, including the screw rod linked together and bolt head, is distributed screw thread in one section of screw rod or whole length;Groove is had on bolt head;Groove is with the axle of screw rod as axis of symmetry, its size and shape is constant to bottom land from notch, eliminate conventional bolt head and people is tripped the potential safety hazard causing traumatic injury, industrial injury etc., be simultaneous for termination slotting bolt and be equipped with associated spanner, the fixed block that including handle and is connected with handle, movable block.The front end of handle is respectively equipped with rotating shaft, chute, and its end is provided with uropore;The bottom of movable block is provided with tooth bar, and this tooth bar is located in chute;Rotating shaft is provided with band tooth regulation wheel, and this band tooth regulation wheel is provided with tooth;Tooth bar is meshed with tooth;A cylinder it is respectively provided with on fixed block and movable block, this cylinder one_to_one corresponding is perpendicular to fixed block, movable block, associated spanner is by adjusting the distance between two cylinders to adapt to the length of the groove on bolt head, two cylinders are inserted in the groove of bolt head, can flush with fixation surface and not appear or to unscrew bolt under even by precession bolt to its bolt head end face.Above-mentioned termination slotting bolt is in addition to needs associated spanner completes to install, if running into large-area fixed panel, and its groove being rotated in by associated spanner, the nut under being also secured to again, remove and install unusual inconvenience.
Utility model content
In order to solve the problems referred to above that prior art exists, this utility model provides a kind of easy for installation and labour-saving bolt.
The technical scheme that this utility model is used is:
A kind of bolt, including head 1 and screw rod integrated with described head 2, described screw rod 2 is for being provided with externally threaded cylinder, and described screw rod 2 is provided with restriction nut and the homodromal position-limit mechanism of bolt.
Described position-limit mechanism is the through hole 4 radially and running through setting along described screw rod 2 near the tail end direction of described screw rod 2.
Described position-limit mechanism is the first groove 3 offered along bolt-center direction of principal axis at described screw rod 2 tail end.
Described position-limit mechanism is radially and to run through the through hole 4 offered, and the first groove 3 offered at described screw rod 2 tail end along bolt-center direction of principal axis near the tail end direction of described screw rod 2 along described screw rod 2.
The grooved of described first groove 3 is yi word pattern, Triangle ID type, interior angle square, cross, rice font or interior hexangle type.
When the grooved of described first groove 3 is yi word pattern, its length is less than or equal to the diameter of described screw rod 2.
Described head 1 is turret head, round end, square spigot or countersunk head.
Described external screw thread is the one in full thread and non-full thread.
It is further opened with the second groove 5 along its central axis direction on head 1 top of described bolt.
The grooved of described second groove 5 is identical with the grooved of described first groove 3.
The beneficial effects of the utility model are: this utility model when being fastenedly connected the bigger plane with through hole with nut, put forth effort without the laborious both sides up and down in bigger plane are fixing, only by being arranged on the first groove of screw rod tail or the through hole of setting need to be run through along screw rod radial direction, i.e. can use extracting tool to insert in the first groove or in hole, utilize lever principle in the laborsaving installation and removal in the same side of bigger plane;In this utility model, the setting of through hole is without kit, and the suitable shaft in any aperture all can mount and dismount;Bolt simple modifications present in prior art can be used by this utility model, cost-effective, easy to use, it is simple to promote and use.
