A clamp with liner and mounting base are provided for the attachment of control lines to a subsea riser. The clamp comprises an upper clamp half and a lower clamp half. Each clamp half is hingedly connected along a hinge edge of each clamp half to the other clamp half and latchably connected along a latch edge of each clamp half to the other clamp half by latch structure carried by each clamp half. The latch structure carried by the upper clamp half comprises a pair of parallel ears protruding transversely away from the latch edge of the upper clamp half and defining a pair of aligned boreholes, a pivot pin having a transverse borehole carried by the aligned boreholes through the ears, a bolt carried in the transverse borehole through the pivot pin, and a toggle bar having a threaded transverse borehole therethrough threadably mounted on the bolt. The latch structure carried by the lower clamp half comprises a pair of parallel ears protruding transversely from the latch edge of the lower clamp half and defining a pair of saddles facing away from the upper clamp half and contoured for close receipt of the toggle bar. Each clamp half has an inner surface defining a laterally bounded depression for receiving and locating a liner element having a portion shaped to fit the depression.

The invention relates to a punching device, and especially relates to an orthopedic surgery positioning punching device. The technical problem of the present invention is to provide an orthopaedic surgical positioning and punching device which can stably punch a drill bit, stably adjust a drilling angle, and has a support device capable of alleviating pain. A technical scheme: an orthopedic surgical position punching device comprise a base, a tail, a first bearing seat, an upper L-shaped cylindrical rod, a first limit block, a compression spring, a sleeve, a plug, a second bearing seat, a first pinion, etc. A tail seat is arrange on that right side of the base, a first bearing seat is arrange on the upper part of the tail seat, and an upper L-shaped cylindrical rod is arranged in the firstbearing seat. As that plug block is arrange, the plug block contacts with the first pinion gear when people do not use the equipment, so that the first pinion gear can be prevented from move at willon the semi-ring gear, and as the toggle bar is arranged, the sleeve can be driven to move by rotating the toggle bar, so that the equipment can carry out subsequent work and is convenient for peopleto operate.

In a toggle bar link (100) for conveyor pans of conveyors or guideway pans of extraction machine guideways, with toggle bar sockets (1) arranged at the sides of the pans in whose socket cut-outs (3) a toggle bar can be inserted and retained by securing elements (4), both the toggle bar (2) and the securing elements (4) as well as the toggle bar sockets (1) are constructed intrinsically symmetrically and the toggle bar sockets (1) are arranged symmetrical to a plane of symmetry (S) running through the joint between the pans. Owing to the symmetrical construction of the individual parts they can not only be produced simply but also no orientation problems are posed in the assembly of the individual parts.

The present invention relates to a spanner having a toggle bar installed in at least a jaw and allowed to be rotated in one direction for tightening or releasing a bolt (or nut) continually by continuous operation of rotating the spanner's lever in one and converse directions repeatedly in a state of gripping the bolt, also easily operative for tightening or releasing a bolt (or nut), especially, placed in a narrow gap. The spanner is constructed to comprises a lever; a first jaw and a second jaw respectively extending from both sides of the lead end of the lever and forming a gripping space therebetween for gripping a bolt; a toggle bar installed on the lead end of the second jaw to be allowed to be rotated only to outward of the gripping space; a tension adjustment bolt installed in the long hole formed on the bottom of the second jaw and having a lead end connected to the inner side of the toggle bar so as to elastically support the toggle bar to inward of the gripping space.

A shutter having a frame, hollow louvres rotatably supported in the frame, and a control bar for controlling the louvres and one-piece connector members connecting the louvres to the control bar in which the connector member has a T-member with integral rigid arms extending normal to the stem on either side for insertion into a louvre, a stem integral with the T-member and an abutment on the stem which prevents movement of the stem into the interior of the louvre and ribs within the louvre for locating the arms and assisting in providing a hinge action and attachments for attaching to a control bar.

The invention discloses a pick-type metal rod counting device, which comprises a fixed base plate and a counting shift block, a pair of adjustment notches are arranged at the tail of the fixed base plate, and a rotating A through hole, a limit post and a counting electric eye. When the metal rod rolls, the dial is moved, and the entire counting dial swings counterclockwise, and the counting bar passes through the counting electric eye, and the counter counts by one at this time. After the metal rod passes through the feeding trough, under the action of the counterweight, the counting shift block swings clockwise to reset, and the counting bar touches the limit column head, and starts to prepare for the next counting. The paddle-type metal rod piece counting device has the advantages of simple structure, reliable counting, low cost and strong practicability.

An apparatus for manufacturing the cover of manhole on boiler is composed of a base, a fixed axle to the base, a worm-gear set connected to said fixed axle, two slide blocks on the top end of said fixed axle, a toggle bar unit on said worm-gear set, and a machining table with the slot of toggle bar on its lower part, the cross slot for holding said slide blocks and the workpiece fixing holes on its surface. Its manufacture method is also disclosed.

The invention relates to a straw plucking harvester comprising a traction device, a transmission system, a feeding chain harrow, a straw plucking device, a scraper type conveying device, a frame, a straw tank, and a ground wheel. The traction device is arranged on the front side of the machine. The feeding chain harrow is arranged on the back side of the traction device. The straw plucking device is arranged on the back side of the feeding device. The scraper type conveying device is arranged on the back side of the straw plucking device. The straw tank is arranged on the back side of the scraper type conveying device. The straw plucking device is composed of an upper straw plucking roller, a lower straw plucking roller, and compacting devices which are arranged on the two ends of the upper straw plucking roller. Under the effect of the compacting device, the upper straw plucking roller is pressed on the upper side of the lower straw plucking device. A groove is axially provided on the surface of the upper straw plucking roller. The feeding chain harrow is composed of a chain, a toggle bar, a front feeding chain wheel, a back feeding chain wheel, and a lower feeding chain wheel. The toggle bar is arranged on the chain. The lower feeding chain wheel is coaxial with the upper straw plucking roller. The straw plucking harvester provided by the invention has the advantages of simple structure and high straw plucking rate. During working, straw alignment is not needed. With the harvester, a working requirement of whole straw plucking recovery can be satisfied.
