The manufacture method of the thumb sleeve pipe of bar bender
Technical field
A manufacture method for the thumb sleeve pipe of bar bender, belongs to special tool field.
Background technology
As everyone knows, bar bender on building site, bend in shaping process at stirrup (general diameter is lower than 14), always by several reinforcing bars on platform after marshalling once (bending machine) bend shaping, increase work efficiency with this.But upper at palm of the shorter and position of the thumb due to staff, the length of thumb and forefinger is made to differ one section, therefore, think that once arranging more reinforcing bar just has any problem, if extend the length of thumb, make it reach the length of forefinger, this will be conducive to many by reinforcing bar, and be conducive to reinforcing bar in finger seam to lower and on shape in a row, thus to increase work efficiency.
Summary of the invention
The object of the application is the manufacture method of the thumb sleeve pipe that will provide a kind of bar bender, realizes above-mentioned object with this.The effective metal of this cover or plastic material are made.It is characterized in that: the length (after putting) of sleeve pipe can reach the length of forefinger tip, and the main body of sleeve pipe selects the pipe of one section of Rotary-table, and the top of sleeve pipe is done in the arc-shaped, to facilitate touch reinforcing bar.Be drilled with aperture in the middle of cannula tip, aperture for ventilation so that the hand perspiration of the thumb that leaves.The snap close for being connected with thumb is provided with in the bottom of sleeve pipe, the shape of snap close is the Rotary-table of one section of distinguish, longitudinally several saw kerfs are sawed out in direction by this section of sleeve pipe, after making this section of sleeve pipe become several identical fritters (point break), each lobe of snap close all has inward collapsible and outwardly elastomeric deformable.Possess on the top of snap close a circle outwards curling and formed shackle, rubber band in shackle inner sleeve, rubber band is fixed on shackle place, and rubber band can free shrink activity in shackle, the elasticity of rubber band can make snap close inwardly tighten up, and with this, sleeve pipe is connected as a body by the prosthomere of snap close and thumb.
During use, above-mentioned sleeve pipe is worn on the thumb of both hands, after a thread reinforcing bar is picked up, be easy under the help of platform, by the crack that the sleeve pipe on thumb becomes with other four finger-type, to lower and on arrangement of bar is neat after once complete the operation of bending and molding, thus to increase work efficiency.Facts have proved, after putting on sleeve pipe, each amount of reinforcing bar of taking has exceeded original 1/3rd more, very convenient and practical.

Detailed description of the invention
As shown in Figure 1, the manufacture method of the thumb sleeve pipe of a kind of bar bender, this sleeve pipe 1 metal or plastic material are made.The length of sleeve pipe 1 can reach the finger tip length of forefinger 2, and the main body of sleeve pipe 1 selects the pipe of one section of Rotary-table, and the top of sleeve pipe 1 is done in the arc-shaped, to facilitate touch reinforcing bar.Be drilled with aperture 3 in the middle on sleeve pipe 1 top, aperture 3 for ventilation so that the hand perspiration of the thumb 4 that leaves.The snap close 5 for being connected with thumb 4 is provided with in the bottom of sleeve pipe 1, the shape of snap close 5 is the Rotary-table of one section of distinguish, longitudinally several saw kerfs are sawed out in direction by this section of sleeve pipe 1, after making this section of sleeve pipe 1 become several identical fritters (point break), each lobe of snap close 5 all has inward collapsible and outwardly elastomeric deformable.Possess on the top of snap close 5 circle outwards curling and formed shackle 6, rubber band 7 in shackle 6 inner sleeve, rubber band 7 is fixed on shackle 6 place, rubber band 7 can free shrink activity in shackle 6, the elasticity of rubber band 7 can make snap close 5 inwardly tighten up, and with this, sleeve pipe 1 is connected as a body by the prosthomere of snap close 5 and thumb 4.
During use, above-mentioned sleeve pipe 1 is worn on the thumb 4 of both hands, after a thread reinforcing bar is picked up, be easy under the help of platform, by the crack that the sleeve pipe on thumb 4 becomes with other four finger-type, to lower and on arrangement of bar is neat after once complete the operation of bending and molding, thus to increase work efficiency.Facts have proved, after putting on sleeve pipe 1, each amount of reinforcing bar of taking has exceeded original 1/3rd more, very convenient and practical.
