Description

A kind of device of tying up

Technical field

The utility model relates to a kind of building operations instrument.

Background technology

When making the mixed earth braiding of reinforcing bar steel mesh reinforcement, building, highway etc. need tie up silk.The instrument that the workman uses always is the cleek of class " J " shape, and two of soft iron silk on the elbow of cleek " J " shape, is rotated by hand about " J " shape cleek two circles, and the soft iron silk twines with tighten two reinforcing bars.Have following shortcoming in this process: 1, many how consuming time " J " shape cleek dependence hand-screw take two turns, so efficient is low; 2, " J " cleek rotates long afterwards wrist and the palm of the hand and aches in the palm of the hand, operates very inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of device of tying up.

The utility model is a kind of device of tying up, one support 4 is arranged, triangle stand 4 ' two ends be installed on the support 4, two pincers handles 1 the middle part respectively by a center pin 3 be installed in triangle stand 4 ' on, the two ends of stage clip 2 are installed in respectively on two pincers handles 1, an end that rotates cleek 6 is fixed on the end face of gear 8, two tooth bars 5 are embedded in respectively in the dovetail groove of offering in the support 4 10, gear 8 and two tooth bar 5 engagements, in that being housed on two tooth bars 5,9, two pins 9 of pin are embedded in falling in the groove 7 of corresponding pincers handle 1 end respectively respectively.

The utility model is compared with technical background, has some advantage: 1. once clamp handle by holding with a firm grip and just can tie up once silk, compare and improved efficient under the technical background greatly, 2. simple to operate and convenient, 3. whole frame for movement is simple, safe, be easy to make.

The specific embodiment

As shown in Figure 1, the utility model is a kind of device of tying up, and a support 4 is arranged, triangle stand 4 ' two ends be installed on the support 4, two pincers handles 1 the middle part respectively by a center pin 3 be installed in triangle stand 4 ' on, the two ends of stage clip 2 be installed in respectively two pincers handles 1 on.As shown in Figure 2, two tooth bars 5 are embedded in respectively in the dovetail groove of offering in the support 4 10.Shown in Fig. 3 (e), an end that rotates cleek 6 is fixed on the end face of gear 8, shown in Fig. 3 (c), and gear 8 and two tooth bar 5 engagements.Shown in Fig. 3 (d), on two tooth bars 5, pin 9 is housed respectively, shown in Fig. 3 (b), Fig. 3 (d), two pins 9 are embedded in respectively in the groove 7 of corresponding pincers handle 1 end.

The course of work of the present utility model is as follows:

Hold pincers handle 1 with the right hand, left hand is entangled in two of soft iron silk on the rotation cleek 6, after twining surely, the right hand firmly closes up two pincers handles 1, compress stage clip 2, clamping handle 1 this moment rotates around center pin 3, by the pin 9 on the 7 drive tooth bars 5 of the groove on the pincers handle 1, make in the dovetail groove 10 of tooth bar 5 in support 4 and move, the gear 8 that the drive of tooth bar 5 is engaged with rotates, gear 8 drives rotation cleek 6 and rotates together, rotates cleek 6 the soft iron silk is twined three circles with tighten two reinforcing bars, behind the tighten, rotate cleek along oppositely from the soft iron silk, taking out of the hook that rotates cleek 6, stage clip 2 meetings that compress this moment promote pincers handle 1 automatically and reset, and reverse all component that drive that reset of pincers handle 1 reset, and form the once complete course of work.

Claims (1)

1, a kind of device of tying up, one support (4) is arranged, the two ends of triangle stand (4 ') are installed on the support (4), the middle part of two pincers handles (1) is installed in the triangle stand (4 ') by a center pin (3) respectively, the two ends of stage clip (2) are installed in respectively on two pincers handles (1), it is characterized in that an end that rotates cleek (6) is fixed on the end face of gear (8), two tooth bars (5) are embedded in respectively on the dovetail groove of offering in the support (4) (10), gear (8) and two tooth bars (5) engagement, pin (9) is housed on two tooth bars (5) respectively, and two pins (9) are embedded in respectively in the groove (6) of corresponding pincers handle (1) end.
