Embodiment Construction
[0009] according to figure 1 , the tapered sleeve locking folding handle riser includes a tapered sleeve 1, a riser 2, a tapered head piece 3, a handle bolt 4, a guide lock 5, an oblique hook 6, a hoop 7, and two ears Sheet 8 and axle seat 9.
[0010] The tapered sleeve 1 is a circular tube that expands at one end to form a tapered sleeve, and the other end lathe processes the connection port, and then tightly fits with the vertical pipe 2. There is a groove at the top of the vertical pipe, and the tapered At the joint between the type sleeve 1 and the standpipe 2, there are two pairs of perforations in parallel up and down, and a locking surplus hole is opened in the middle of the tapered sleeve 1 below the up and down parallel pairs of perforations.
[0011] The conical head piece 3 includes a conical head 31 and an inner extension tube 32. The conical head 31 is formed by first expanding a section of circular tube and then shrinking the tube. The upper part of the conical ...

The invention discloses a taper sleeve locking type folding handle riser which comprises a conical sleeve, a riser, a conical head member, a bolt with a handle, a guide pin, an oblique hook, a hoop, a double-lug piece and a shaft seat, and is characterized in that: the conical sleeve is of a taper sleeve shape formed by expanding one end of a round tube, and the other end of the round tube is firmly matched and sleeved with the riser; the conical head member comprises a conical head and an inward-extension tube; the conical head is matched with the conical sleeve and firmly matched and sleeved with the inward-extension tube; the hoop is hooped on the neck part of the conical head; the double-lug piece is locked by the hoop; the shaft seat is connected with the bottom of the conical sleeveand can be in sliding connection with a slot hole of the double-lug piece through a pair-lock bolt; the bolt with a handle is rotatably positioned and connected to the sleeve joint between the riser and the conical sleeve; the guide pin is riveted above the bolt with a handle and is parallel with the bolt with a handle; the oblique hook is connected to the guide pin and the bolt with a handle andmatched with a hole on the conical head; and the conical head and the conical sleeve can be firmly locked.
Description
Technical field: [0001] The invention relates to a folding handle riser, in particular to a taper sleeve locking type folding handle riser technical background: [0002] At present, it is difficult to find the folding handle riser of the tapered sleeve locking type for the folding handle riser on the market. The designer first designed the "taper sleeve type locking structure folding handle rod", although the tapered sleeve locking scheme was proposed, But in terms of structure, there is room for improvement in the production process. Invention content: [0003] The purpose of the present invention is to provide a more complete structure, simpler production process, and more convenient for industrial production of the tapered sleeve locking folding handle riser, the purpose of the present invention is achieved in this way. Taper sleeve locking folding handle riser, including taper sleeve, riser, taper head piece, bolt with handle, guide pin, oblique hook, hoop, double l...
